What is Open Die Forging? | Metal Manufacturing

Rolled ring forging, closed die forging, and open die forging are three of the most common metalworking processes. Although they are all forging methods, they are also all different. It is important to be able to tell these processes apart in order to determine which fits your specific needs. To help you out, here is everything you need to know about open die forging.

What You Need To Know About Open Die Forging

Open die forging, also known as free forging, is a metalworking process. It takes heated metal and compresses it between two dies. The metal is worked at temperatures ranging from 500°F to 2400°F and is shaped into the desired shape through hammering or pressing. Most of these forgings or made on flat dies, but V-dies, round swaging dies, pins, mandrels, and loose tools are also used depending on the specific part.

This method is very similar to the closed die forging process. However, open die forging is unique because the shape of the piece does not result from the shape of the dies used, but from repeated local forming with geometrically simple dies that are typically moved relative to the piece. This forging process gets it’s name because the metal is never completely confined in the dies.

Open die forgings produce strong, durable parts in sizes that range from a few pounds to hundreds of tons. As a result, it is a favorable method to produce large and simple parts such as bars, rings, blanks, hollows, and spindles. Open die forging is also a great open for custom metal components as well.
